Title: Temperature regulator for an electrical heating device incor porating a protective circuit
IPC: G03D15/02
Filed: 1974-02-08
Abstract: 1444041 Automatic control of temperature FUJI XEROX CO Ltd 8 Feb 1974 [21 June 1973] 05985/74 Heading G3R In a retroactive system controlling the temperature of a heater 1 by means of a temperature detector such as a thermocouple 5 feeding a signal via wires 6, 7 to a regulator 4 which controls the heater current, e.g. by controlling the triggering of triac 2, the detector 5 is electrically connected to the heater and draws current from power supply 3, the system being such that if the detector becomes detached from the heater, this current drops to zero and cuts off the main heater current to prevent overheating. As described the system controls a thermal fixer in an electro-photographic duplicator. The output of the regulator 4 is fed to a pulse transformer 9 via relay contacts 8b. These contacts are normally held closed by thyristor 10 being turned ON by a current tapped from the wires 6, 7 and passing through resistors R 1 -R 3 . If the thermocouple 5 becomes detached, the triac 2 is turned OFF by opening of the contacts 8b. Instead of direct connections to the wires 6, 7, capacitive or transformer coupling may be used Figs. 2, 3 (not shown).

Title: Improvements in or relating to the refining treatment of hydrocarbon oils
IPC: C10G29/12
Filed: 1932-03-07
Abstract: Hydrocarbon motor - fuels are purified by treatment of the vapour with hydrochloric acid in presence of a solid contact material containing free or/and combined metal adapted to catalyse the action of the acid.  Mixtures of one or more electro-positive metals or salts thereof with one or more electronegative metals or salts thereof are especially efficient. Treatment with sulphuric acid may follow, and steam and air or other oxygen-containing gas may be used with the hydrochloric acid gas or aqueous solution.  Contact materials specified are clays, fuller's earth, bauxite, diatomaceous earth, silica fragments, and silica gel; they may be mixed with metal oxychlorides, Portland cement, litharge and glycerine, or waterglass and sand, allowed to set, and then reground.  The catalytic mass may be activated or reconditioned by treatment with hydrochloric acid gas or aqueous solution.  In examples, granulated copper or zinc, iron or brass turnings, mechanical mixtures of copper with iron or zinc, chlorides of tin, iron, or zinc, and mixtures of naturally recurring minerals or ores, are used with 0,4-4,0 lb. of acid as vapour or as 20 per cent solution.  The sulphuric acid may be of 93 per cent strength.  Suitably, cracked or other vapours are passed by pipe 1 to a fractionator 3, the gasoline is condensed, and is collected in a receiver 9 from which gases are released through a pipe 34.  Part of the condensate may be returned to the fractionator through a pipe 10, pump 12, and pipe 13 to control the B.P. range of the issuing vapours.  The remaining condensate is passed by a pipe 36, pump 38, and pipe 39 to a stabilizer 41 in which it is heated by a coil 26 to drive off very light hydrocarbons, any remaining fixed gases, and hydrogen sulphide through a pipe 42.  It is then passed by a pipe 44 to a heat exchanger 31 in which it is vaporized, and by a pipe 46 and a pipe 48 or a pipe 50 to the treater 61 packed with the contact mass. The hydrochloric acid is forced by a pump 54 through a pipe 55 and a pipe 57 or a pipe 59 so as to pass with the hydrocarbon vapours through the treater.  The vapours flow by a pipe 69 or a pipe 67 to a fractionator 71, thence to a condenser 74 and a receiver 77 from which part of the condensate may be pumped through pipes 82, 85 back to the fractionator 71.  The sludges from the treater 61 and heavy refluxes from the fractionator 71 are passed to a receiver 89.  The vapours from the treater 61 may be neutralized by ammonia or caustic alkalies or filtered or otherwise separated from entrained liquids before entering the fractionator 71.  The heating of the hydrocarbon in the stabilizer 41 and exchanger 31 is preferably effected by the refluxes from the fractionator 3.  These refluxes are forced by a pump 17 through pipes 18, 20, 24 to the coil 26 and back to the fractionator through a pipe 27, or usually through pipes 18, 20, 15<1>, a heating coil 17<1>, pipes 19<1>, 20, and pipes 24, 29 leading respectively to the coil 26 and the exchanger 31.
